After four gruelling rounds of Six Nations fixtures, Ireland are the only team who can pip France to the title on the final weekend after they beat England at Twickenham for the first time in four years.
Andy Farrell's side revelled late to secure a bonus-point win at Headquarters, although England's dignity remains well intact considering they played 78 minutes with 14 men following Charlie Ewels' early red card.
In a poetic twist, Ireland will now need to don their English supporter caps given Eddie Jones ' side would still need to beat France in Paris next Saturday in order for them to finish atop the pile.
